激发态气体中的亚稳微分子
Metastable Quasimolecules in Excited Gases
摘要：
被认为是由两个不同的原子在共振激发气体中激发的双分子。在偶极-偶极相互作用算符的帮助下，在量子力学微扰理论的一阶中计算了这些分子的解离能和典型尺寸。结果表明，存在亚稳准分子，其向基态（两个非激发原子）的偶极辐射跃迁是被禁止的。这种分子的寿命估计，它表明，准分子可能会大大影响共振激发气体中的输运过程。
英文摘要：
Quasimolecules, which consist of two differently excited atoms in a resonantly excited gas, are considered. The energy of dissociation and typical sizes of such molecules are calculated in the first order of quantum-mechanical perturbation theory with the help of the dipole-dipole interaction operator. It is shown that there exist metastable quasimolecules, whose dipole radiative transition to the ground state (two non-excited atoms) is forbidden. The lifetime of such molecules is estimated and it is shown that quasimolecules may considerably affect the transport processes in a resonantly excited gas.
